IMPROVEMENT IN DUMPlNG-CRS.

Specification forming part of Letters Patent No. 107,683, dated September 27, 1870.

i To all whom 'it may concern:

drawing, forming part of this specification.

This invention "relates to improvements in dumping-cars 5 andi consists in arranging the boxes with one side or end, as the case may be, sloping from about the center of the bottom upward, and providing the sloping side with rockers, on Whichthe box, in tilting, will roll toward the edge for dumping instead oi' tilting on hinges, as heretofore.

The said rockers are provided with flanges,

`to keep them on the rails whereon they roll, vand they have chains attached to their ends and to the truck-frame in a way to prevent the-1n from sliding on the rails they roll upon.

Figure 1 is a side elevation of my improved.

dumpingcar;` and Fig. 2 is an end view of the same, the box being partly broken out.

Similar letters of reference indicate corre- Y Sponding parts.

A is the frame ot`- the truck, with cross-rails B. C is the box, one side of which, D, slopes `from about the plane of the center upward. represents the rockers, placed on the said slopin g Side, and arranged to roll on the rails B. The rockers are so shaped (being curved eccentrically, `the radii lessening from the bottom up) that in dumpingthe car the center of gravity of lcar-boxandload jointly (which center of gravity changes in the act of dumping by the gradual running out of the load) remains perpendicularly supported, or nearly so.

F represents chains attached to the rockers and to the rails in such a way that the rollers willbe prevented from slipping along the rails either Way from the position they should occupy. The rockers have lianges G, to prevent end movement of the box.

H is a locking-pin to secure the box to the truck When receiving and carrying the load. I is a chain to prevent the box from turning too far.

The box being iilled level full, the same Will require no power in theory, or very little in practice, for dumping, nor for holding it back from dumping too Sudden. Of course, the boxes may be arranged todump at the side or end of the car, as preferred.

It is an essential advantage of the arrangement that the center of gravity of the box and load be over the center of the truck, which would not be the case if the load had to be adj ustedion the sloping side, as with dumpingboxes with hinges, and if the rockers are not curved, as described, the dumping will require power at some position of the box, and at other positions it' Would fall over suddenly and be damaged or broken. NOW, these boxes may be so constructed that they will either -not dump without the application of a little power, or Will dump by the action of gravity as soon as the fastening-hook is taken out. In the latter case they should be held back a little by hand. For very heavy cars any known contrivance-a Windlass, forinstance may be used. In all cases the principle 111-.

volved in the curving of the rockers is to be employed.

It is well known to me that a car can .be made .dumping to both sides by making the box sloping on both sides and using rockers, chains, and locking-pins, &c., on both sides,'on the saine principle of the car above described.

Having thus described my invention, I claim as new and desire to secure by Letters Patentv 'Ihe sloping car-box C, eccentrically-curved rockers E, rails B, and chains F, all combined and arranged together and with the truck of a car, all substantially as specified.
